Derek Rosa, 13, stabbed his mother 46 times, lead Hialeah detective testifies

He told detectives he called mother homophobic slur before killing her, they say

MIAMI-DADE COUNTY, Fla. ā€“ A Miami-Dade County judge is expected to decide Friday whether Derek Rosa, 13, who is accused of killing his mother, Irina Garcia, 39, in October will be transferred back to juvenile detention.

Rosaā€™s attorneys began calling witnesses Thursday as they made their case about how they say his rights are being violated by being held at the adult Metrowest Detention Center.

One of those witnesses was Detective Joseph Elosegui, with the Hialeah Police Departmentā€™s Major Crimes Unit, who testified that Garcia had 46 stab wounds all over her body, and the only parts of her body that didnā€™t have stab wounds were behind her knees.

Elosequi also testified that further investigation showed that Rosa made six Google searches on the evening of his motherā€™s death. Those searches included:

ā€œThe carotid artery image diagram.ā€

ā€œWhat is the best place to stab someone?ā€

ā€œIs a small knife good for killing?ā€

ā€œIs it easier to kill someone with a small knife?ā€

ā€œCan a knife cut through bone?ā€

The last search was to inquire about a machine gun.

Detectives also said Rosa told police in a confession that he called his mother ā€œmaricona,ā€ a gay slur in Spanish, just before he stabbed her.

5:30 p.m. live report:

Corporal Cyrim Wimbs, a corrections officer from the Metrowest Detention Center, testified that Rosa is under protective custody and is ā€œflourishing.ā€

The Department of Corrections said they are always watching Rosa because heā€™s considered a high-profile inmate. The teen is kept alone in a cell with a frosted window with no direct view outside.

While in court Thursday, Wimbs testified that Rosa is able to regularly speak with his family and is allowed to have minimal interaction with one inmate. He also said that Rosa was allowed to play basketball and football with the other inmate.

He also said Rosa is constantly monitored by mental health specialists who look for red flags.

Dr. Gina Bettica, a psychologist with Jackson Health Systemā€™s Correctional Health Services, said Rosa has ADHD and that another doctor tested him on the autism spectrum. She also testified that Rosa was suicidal when he was first arrested.

Last week, the Miami-Dade State Attorneyā€™s Office released crime scene photos related to the case.

Multiple photos showing the murder weapon ā€“ a knife with its tip cut off ā€“ were released, along with surveillance images showing the victim, Garcia, holding her newborn daughter, and also of her son later standing over her.

Rosa is accused of fatally stabbing his mother as she slept next to his 14-day-old half-sister on Oct. 12.

He has pleaded not guilty after a grand jury indicted the honor roll student on a first-degree murder charge.

Police said Rosa called 911 just after 11:30 p.m. on the night of the killing to report that he had just murdered his mother at their apartment at 211 W. 79th Place. An arrest report states that officers found Garcia lying on the ground with multiple stab wounds to her neck.

Rosa told a 911 dispatcher that he sent photos of the crime scene to an online friend and told him ā€œgoodbye.ā€

One crime scene photo released by the state attorneyā€™s office pictures Rosa with his tongue sticking out, which they said he sent to a friend after the killing.

Police havenā€™t yet publicly identified a motive for the murder.

He is currently being held without bond at the Metrowest Detention Center.

He is being represented by attorney Jose Baez, whose previous high-profile clients included Casey Anthony, Aaron Hernandez and Harvey Weinstein.
